Application filed January 22, 1910. Serial No. 539,490.

To all whom it may concern.

Be it known that l, JOHN B. HAoinvin', a citizen of the United States, residing at Swainpscott, in the ctnlntycf Essex and State of Massachusetts, have invented certain Improvements in Machines for Operating on the Sole Edges of Roots and Shoes, of which the following description, in con nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to a machine for operating on the sole edges of boots and shoes.

In welt shoes, as ordinarily made, the line of stitches by which the outsole and welt are united usually shows on the upper surface of the welt. In manufacturing some kinds of shoes, 1 articularly certain. styles of womens shoes, it is desirable to conceal this line of stitches and it is the primary object of this invention to provide a machine by which this result may be eii ected.

To this end one feature of the invention consists in the provision of a rotary tool constructed and arranged to operate upon some of the stock bacln wardly and upwardly-over the stitches. lln the preferred embodiment of the invention this tool is of frusto conical shape and is provided on its lateral surface with ribs or corrugations which are adapted to rub por tions out the stock backwardly toward the upper.

Another feature of the invention consists in the provision with a tool of the character indicated at a work suppoift arranged to cooperate with the tool in effecting-the result described. Preferably the tool is fixed to a rotary shaft and the work su 'iport is arranged slidably on the same shaft in position to engage the tread face of a shoe sole as it is presented to the tool. Preferably also a spring is arranged tourge the work support toward the tool, suitable stops being provided to limit the movement of the work support toward or from the tool.

A further object of the invention consists in the provision of suitable means for protecting the upper of a shoe from the operation of the tool described. This ineans pret erably consists of a shield positioned adja- Patented May 14:, 1912.

act with the The above and other features of the invention including certam details of construction and cmnbinations ments of parts will be clear] from the aceon'ipanying embodiment of the invention.

a n d arrangey understood description oi one It IS contemplated that it may be desirabl shoes not provided with a we e, in manufacturing certain kinds of lt, to operate on the projectingmargin of the sole in the manner in which upon the welt. it is obvious chine of this invention is form such work. and

and adjacent parts being illustrate the Fig. 3 is a perspective View fragmentary and adjacent parts in atlng upon a has a head 4: bolted provided with bearings supporting a horizontal rotary shaft 8. connected to any suitable belt running l on the shaft A tool 12 is fixed to the forward end ofthc shaft for r0- tative movement therewith and the tool illustrated consists of a shor frusto conical portion having surface a. plurality of ribs or 14. It is not essential that although this design forms a t hub and a on its lateral corrugations the body of the tool shall be frusto conical in shape, very convenlent shape to manufacture. It is preferable,

however, to so form the of the ribs shall lie in the surf as in the tool illustrated. It

tool that the crests ace-0f a cone, 1s preferable,

also, to have the ribs extend diagonally to the elements of the cone in which they lie or, in other words, to have the ribs inclined to the planes passing through the axis of the tool. This arrangement enables the ribs to exert a Wiping action on the welt tending to crowd the stock toward the upper. In order to secure the tool to the shaft it is provided with a threaded aperture 16 adapted to receive a correspondingly threaded stud projecting from the end of the shaft 8.

It will be understood that a variety of shapes or forms of tools may be employed in this machine without departing from the spirit of the invention.

A disk-like work support 18 is slidably mounted on the shaft 8 in the rear of the tool 12 and is provided with an integral sleeve 20 to give -it greater stability. The work support is urged toward the tool by a coiled spring 22 surrounding the sleeve 20 andshaft 8 and abutting against a collar 24 on said shaft. Extending parallel with and above the shaft is a stationary arm 26 secured to the frame-head 4 by a bolt 28 and prevented from turning by an integral flange 30 engaging a shoulder 32 of the head. On its forward end the arm 26 is provided with a vertical guideway in which is received a sliding plate 34 carrying near its lower'end a shield 36 pivotally mounted on the stud 38.- The lower end of the plate is beveled toward the tool 12 as shown in the drawings so that the lower edge of the shield is positioned very close to the ribs or corrugations 14 of the rotating "tool. The plate may be adiusted relative to the tool and arm 26 and is provided for this purpose with a slot 40 through which'a clamping bolt 42 extends. The arm 26 also carries a slide 44 mounted in a horizontal guideway formed in its lower side. The slide may be adjusted along the guideway and may be secured in adjusted position by a bolt 46 threaded thereinto and extending through a slot 48 in the arm with its head resting on the upper side of the arm. On the lower side of the slide is journaled a roll 50 having a beveled face arranged to engage the forward rounded or beveled face of the work support 18 to limit its movement. toward the tool 12. The slide also carries a second stop consisting of a short screw or bolt 52 threaded through a depending portion of .the slide and arranged to engage the rear side of the work support 18 to' limit its movement away from the tool 12. The bolt 52 may be held in adjusted position by a set screw For the purpose of aiding the workmzni in guiding the shoe, particularly in operating around the toe portion, a. linger hook 5G is provided and is adjustably secured to the frame head lby a screw 58. The thrust of the tool against the work tends to slide the distance from the tool.

shaft axially through its bearings and a collar (30 is therefore pinned to the rear end of the shaft to resist this tendency.

Before the shoe is operated upon by this machine it is usually given a rough trimming to even up the edge and leave a uniform width of margin.projecting around the entire forepart. The sole edge is then put. in a softened or tempered condition and is presented to the tool 12 in substantially the position indicated in Fig. 4. The work support may yield as the sole edge is crowded in between it and the tool, or the stops 50 and 52 may be adjusted to hold it at a fixed As the tool 19. rotates the ribs 14 catch portions of the stock and crowd or carry it backwardly and u wardly toward the upper thus covering the stitches as indicated in Fig. 4, and this operation results, as the shoe is fed past the tool, in forming a substantially uniform beveled or inclined margin around the sole edge. The shoe may then be given a final trimming and the upset welt may be finished on a welt indenting and lnlrnishing machine or in some similar manner.

It will be noted that the shield may rotate idly with the shoe as it is fed past the tool and that it prevents the upper from coming in contact with the tool and becoming marred or otherwise injured thereby.
